    摘要： To obtain a lithium ion secondary battery having excellent charge and discharge characteristics in which electric connection between active material layers and a separator can be maintained without requiring a strong armor metal case, so that it can be made into thin forms having large energy density. Convex parts and concave parts are formed on at least two surfaces among surfaces of a positive electrode active material layer 7 and a negative electrode active material layer 9 both adjacent to a separator 4 and surfaces of the separator 4 facing both of the active material layers 7, 9, and these three means are bonded and closely adhered by an adhesive resin layer 11 and electrically connected by keeping a lithium ion-containing electrolytic solution in the separator 4 and voids 12 formed by a bonded surface 11a of the convex parts and the concave parts.

    摘要： A lithium ion secondary battery. The battery maintains an electrical connection between electrodes without using a firm case and can have an increased energy density at a reduced thickness while exhibiting excellent charge and discharge characteristics. The battery includes a plurality of electrode laminates each having a positive electrode, a negative electrode and a separator. The positive electrode includes a positive electrode active material layer and a positive electrode current collector. The negative electrode includes a negative electrode active material layer and a negative electrode current collector. This separator is impregnated with a lithium ion-containing electrolytic solution and is interposed between the electrodes in intimate contact. The positive electrode, negative electrode and separator are joined together in intimate contact with porous adhesive resin layers having through holes. The through holes are filled with electrolytic solution to connect the positive electrode active material layer, the negative electrode active material layer and the separator layer.

    摘要： Conventional batteries are disadvantageous in that a firm outer case must be used to maintain an electrical connection between electrodes, which has been an obstacle to size reduction. Those in which each electrode and a separator are joined with an adhesive resin suffer from conflict between adhesive strength and battery characteristics, particularly ion conductivity and internal resistivity. To solve these problems, it is an object of the invention to reduce resistance between electrodes, i.e., internal resistance of a battery to improve battery characteristics while securing both insulation function against electron conduction and ion conductivity between electrodes and also to maintain adhesive strength enough to firmly join the electrodes thereby to provide a light, compact and thin battery. The internal resistivity can be diminished by joining a positive electrode and a negative electrode with an adhesive resin layer having at least one adhesive resin layer containing a filler. The adhesive resin layer has pores, which are filled with an electrolytic solution to exhibit sufficient ion conductivity thereby to improve battery characteristics and to retain adhesive strength.
